NHTSA recall campaign
26V079000
What was wrong
Defect
Daimler Trucks North America (DTNA) is recalling certain 2020-2027 Western Star 49X and 2021-2027 Western Star 47X vehicles. A stud connecting the battery to the starter at the frame rail may have been incorrectly installed or may corrode, which can cause a short circuit.
Risk
A short circuit increases the risk of a fire.
Manufacturer remedy
Dealers will repair the studs, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed April 10, 2026. Additional letters will be sent once the final remedy is available, anticipated May 2026. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is F1029. This recall replaces and expands NHTSA recall number 25V326. Vehicles already repaired under the previous recall will need to have the new remedy completed.
